Specification of Letters Patent.

Patented Feb. 8, 1921.

Application filed February 28, 1920. Serial No. 361,938.

To all whom it-may concern Be it known that I, ALBERT VIcroR Hon- NER, a subject of the King of Great Britain, residing at 504 Caledonia avenue, in the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certainnew and useful Improvements in Window Constructions, of which the following is the specification.

'My invention-relates to. improvements in window constructions and the object of the invention is to devise means whereby either sash may be independently removed from the frame for the purpose of cleaning the window and to perform this operation easily and almost instantaneously with a minimum amount of labor and it consists essentially of the arrangement and construction of parts as hereinafter more particularly explained. a

' Figurel is a perspective view of the window frame showing the sashes in the closed position and partly broken away and in section.

Fig. 2' is a sectional plan view taken through the upper sash.

Fig. 3 is an enlarged sectional detail of the latching device employed in connection with my window sash showing it in the locked position.

' Fig. 4 is a similar View to Fig. 3 showing the sash removed and the lock in the unlocked position.

Fig. 5 is a sectional detail through a portion of the window frame, sash guide, and sash.

. Fig. 6 is an edge view of a portion of the window sash showingthe locking lever in section in engagement with the keeper.

In the drawings like characters of reference indicate corresponding parts inthe va rious figures. I

1 indicatesthe windowv frame provided with the usual vertical casing portions 2 and 3, sill 4 and lintel 5. The frame 1 is provided with the usual stop strip 6, parting strip 7 and outer strip 8 forming the usual guide ways 9 and 10 for the upper and lower sash. 11 and 12 are pulleys for the lower sash secured within the casing portions 2 and 3 in the usual manner. 13 and 14 are pulleys also mounted in the casing. portions 2 and 3. 15 are the cords passing over the pulleys 11 and 12 and to which the lower sash is usually connected and 16'and 17 are cords passing over the pulleys l3 and 14 to which the upper sash is usually connected. The opposite ends of the cords 15, 16 and 17 are provided with the usual counter weights (not shown). 18' is a guide strip slidable within the guide way 10 of the window frame. 19 is a similar guide strip slidable within the opposing'guide way 10 located at the outer side of the casing portion 3. The cords 16, 17 are connected to the lower ends of these guide strips as indicated at 20, Fig. 2.

Each guide strip 18 and 19 is-provided with a vertical rabbet 21 at its inner edge and a rabbet 22in proximity to its outer edge forming shouldered portions 23 and 24. 25, 25 -are similar guide strips slidable within the opposing guide ways 9 to the outer ends of which are secured the cords15. The guide strips 25 are provided with vertical rabbets'26 and 27 forming shoulders 28 and 29; 30 is the upper sash the vertical portions 31 and 32 of which are correspondingly rabbeted and shouldered so as to fit into the grooves 21 and 22 and against the shoulders 23 and 24 as the sash is placed between the guide strips 18 and 19. 1

In order to insure of the sash being placed in the correct position as it is placed between the guide strips 18 and 19 I have provided each guide strip'with a tongue 33 extending across the groove 22 the opposing portion of the sash 30 being provided with a cross recess 34 into which the tongue of the guide strip fits. The width of the removable portion of the upper sash must be the same orslightly less than the distance between the parting strips 7 so as'to enable the upper sash to be withdrawn inwardly when removed.

' The guide strips 25 must be of less width at their inner or widest portion than the projecting portion of the parting strips 7 for the same purpose so that the upper sash may pass as it is withdrawn inwardly.

1 35 is the lower sash which is also formed the guide strips-25 and is provided with a to 'fit into the grooved portions 26 and 27 of cross recess 36 into which fits the cross automatically locking the guide strips in r place when the window sash is removed so that they will be held against being carried upward by the sash weights attached there;

. enters into the recess the upper contour of which is. in the form of a notch 42 theouter side of the notch being extended upward at 43. '44 is a slot cut in each guide piece in whichis pivotally mounted a locking lever 45 which is in the form of a bell crank the horizontal arm 46 being hooked in shape so as to extend around and fit the inner rolled portion 41 of the plate 40 when in the locking position. The other arm 47 of the locking lever extends upward normally against the face of the guide way in which the guide strip moves. 48 isa recessformed in the base'of each guide way the upperedge of therecess being provided with a V-shaped notch 49; 50 is a tension spring connecting the horizontal arm 46 of the locking lever to the bottom of the slot 44. p

' Having described the principal parts involved in my invention I will briefly describe the operation of the same. may be first stated that a suitable portion of the frame 1 is provided with an indicating mark such as shown at 51 and the sash with an indicating mark such as shown at 52. Theouter sash is also provided with corresponding indicating marks. When the sash'35 israised so that the'indicating marks 51 and 52 are opposite, the vertical arm of the lever 45 is brought opposite the recess 48, The window sash is then gripped by the operator and drawn directly inward into the room. By this operation the upwardly extendingportion 43 formed at the side of the notch 42 of the plate 40 engages 1 the horizontal arm 46 of the lever 45 tilting this arm of thelver upward against the tension of the spring 50 thereby throwing theupper end of the arm 47 of the lever 45 into the recess 48. As the sash is withdrawn, being held in the hands of the operator; the weight of such sash is relieved andthe sash weights serve to draw the guide strips 25 upward so that the outer end of the lever armj47 engages with the notch 49 and is thereby thrownto its final position enabling the sash to be drawn completely outward and the horizontal arm 46 of the locking lever to pass through the exit orifice 39.. The guides 25 are thus supported in position ready to again receive the window sash after the window has been cleaned.

In inserting the sash all thatit is necessary to do is to place the sash between the guide ways sothat the cross rib 37 enters the cross recess 36, the horizontal arm 46 of the locking lever being inits final .upper position allowing of the up'wardextension 43 of the plate 40 to pass beneath such arm into position. The windowv sash is then drawn down, being connected to the guides tion the upper ends of the arms 47 of the levers are withdrawn from the notches 50 acting to carry the levers again into the locking position in engagement with the notches.42. i

It. will, of course, be understood that the upper sash is similarly operated so as to remove itand replace it in position.

From this description it will be seen that I have devised a very. simple device whereby the sash may be easily withdrawn from the window for the purpose of cleaning which operation may be done very quickly, almost instantaneously and replaced in position by a simple operation which is just as 'instane taneous. i

WhatI claim as my invention is."

1. In a window construction, the combinaopen outer-end, shouldering means" carried by the guide strips against which the window sashbears when inserted therebetween, a horlzontaltongue formed on the inner face of each guide strip and adapted-to en a ter the openzouter end of the'rece ss to fit the recess as the sash is placed in position between the guide stripsyand means for automatically locking the guide strips to the window frame operated by the withdrawal ofthesash.

2. In a window construction, the combination with the window framehavingfguide ways, of a guide strip slidable withineach guide'way. and to which the sash cords and sash weights are adapted to be connected, of a window sash fittingbetween theguide strips and engageable therewith and having a recess in each edge, alever pivoted within each guide strip and entering the recess oi the sash, and means within the recess .of'the sash for forcing the opposite end of the lever into locking engagement with the frame operated by the withdrawal of the sash from between the guide strips.

3. In a window construction,the combination with the window frame having the usual guide ways each provided with a recess in the base thereof, of guide strips slidably fitting within the guide ways and to which the usual sash'cords and weights are adapted to be connected, a window sash fitting between the guide strips and engageable therewith. and having a recess in each vertical edge, a plate secured to each vertical edge of the sash and having-a notched outer end, a bell crank shaped lever mounted within each guide strip the horizontal arm of which is resiliently mounted and provided with a hook engaging the notched plate of the sash and the vertical arm of which is normally in slidable engagement with the bottom of the window frame slide way and adapted to enter the recess of the slide way when brought opposite thereto and as the window sash is withdrawn.
